A big tractor becomes a fuel-hog when used at low power. That because an engine only runs efficently within a certain load-range. A 140 horse tractor used to do a 20 horsepower job will use more fuel than an old 8N Ford gas tractor. That's why tractors need to be sized for the work they do to be efficient.
